GivEnergy 9.5 kWh Battery
A 9.5 kWh low-voltage LiFePO4 battery for GivEnergy's third-generation inverters, stackable up to five units, with a 12-year warranty.
- Best for GivEnergy Gen 3 systems
- Installed battery
- 9.5 kWh
- 12-year warranty
- Energy: 9.5 kWh nominal (186 Ah at 51.2 V) with 100% depth of discharge; no separate usable figure is given.
- A battery only: GivEnergy positions it for its Gen 3 inverter range and does not name models on the pages we read.
- Up to five units in parallel; floor or wall mounted, IP65.
- GivEnergy's datasheet states a 12-year warranty with unlimited cycles; its product page gives a different figure.
Not tested by us
We have not tested the GivEnergy 9.5 kWh Battery. The figures on this page come from the sources listed at the end of the page, checked on 10 November 2026, and we do not show prices. "Best for" is based on what the maker says the product is designed for, not on our own tests.

Specifications
Last checked on 10 November 2026. The grey text under each name explains what the value means.
| Specification | Value |
|---|---|
| Storage | |
| CapacityHow much energy the battery stores. Bigger means longer runtime or more of your own solar power used later. | 9.5 kWh nominal (186 Ah) |
| Usable capacityThe part of the stored energy you can actually use. It is lower than the nominal capacity. | Not stated separately |
| Depth of dischargeHow much of the battery can be emptied without harming it. 90% means 10% is kept in reserve. | 100% |
| Battery chemistryLFP (lithium iron phosphate) cells are known for long life and stable behaviour with heat. | LiFePO4 (LFP), prismatic cells |
| Cycle lifeHow many full charge and discharge cycles the cells are rated for before they hold less than the stated share of their original capacity. | Unlimited cycles within the warranty period (no cycle rating given) |
| ExpansionExtra battery units that add storage to the same system. | Up to five units in parallel, stackable |
| Power | |
| Charge and discharge powerHow fast the battery can take in and give out energy. It sets how many devices it can serve at once. | Continuous charge and discharge current under 120 A at 51.2 V nominal; GivEnergy gives no kW figure |
| Round-trip efficiencyThe share of the energy you put in that comes back out. The rest is lost as heat. | Not stated in the sources we read |
| Backup in a power cutWhether it can keep selected circuits running during a grid outage. | Depends on the inverter: the battery itself is not an inverter |
| Solar | |
| Solar inverterTurns the DC power from solar panels into AC for the home. Built in means no separate solar inverter is needed. | None: this is the battery only. GivEnergy says it is for its third-generation inverter range |
| Connection and housing | |
| Grid connectionThe supply type it is built for. Check it matches your home's supply. | Not applicable: the battery connects to an inverter (51.2 V nominal, 44.8-57.6 V operating range, low-voltage DC) |
| Dimensions (W × H × D)Width, height and depth of the unit, so you can check that it fits. | 480 × 576 × 225 mm |
| WeightMatters for lifting, wall mounting and moving it. | 85 ± 2 kg |
| Protection ratingIP ratings show protection from dust and water. IP55 and IP65 are rated for outdoor-style exposure; check the installation guidance. | IP65, IK10 impact rating, protection class 1; floor or wall mounting |
| Operating temperatureThe range it is rated to work in. Cold and heat can reduce performance. | Charging 0 to 50 °C; discharging -10 to 50 °C; storage -20 to 50 °C |
| ConnectivityHow you monitor and control it, usually through an app. | RS485, USB and CAN interfaces; Modbus and CANbus protocols |
| CertificationsSafety and grid standards the maker says the product meets. | IEC 62619, IEC 62040, CE, UKCA, UN 38.3, CEC-AU |
| Warranty | |
| WarrantyThe period the maker covers. Read the terms: conditions and capacity guarantees differ. | 12 years, unlimited cycles (per the datasheet) |
Compatible with
What GivEnergy says this product works with. Anything not listed here is not confirmed.
- Inverters
- GivEnergy says the battery is for its third-generation (Gen 3) inverter range. It does not list individual models on the pages we read.
- Expansion
- Up to five units in parallel.
- Mounting
- Floor or wall mounting.
Rules where you live
An installed battery normally needs a qualified electrician, and in many countries you must also tell your grid operator, especially if it can export. Rules, incentives and tax treatment differ by country: see our country guides for what applies where you live.
Strengths and things to check
Strengths
- 9.5 kWh in a single unit
- 100% depth of discharge
- Up to five units in parallel
- IP65, floor or wall mounting
- 12-year warranty per the datasheet
Worth checking before you buy
- A battery only: you need a compatible GivEnergy inverter as well
- Heavy at 85 kg per unit
- No efficiency or cycle rating is given
- GivEnergy's own pages disagree on weight, size and warranty length
Change log
We record changes to this page here, so you can see when figures such as the warranty were last updated.
- 10 November 2026
- Page published. Warranty at publication: 12 years (GivEnergy UK datasheet, Gen 3 v2). This page covers the Gen 3 battery, not the Gen 2 or the 5.12 kWh model.
Where this information comes from
We have not tested this battery. Every figure above comes from GivEnergy's UK datasheet for the Giv-Bat 9.5 Gen 3 (version 2, March 2026) and its low-voltage batteries page, last checked on 10 November 2026. GivEnergy's Gen 3 product page lists different dimensions and weight and a different warranty length from the datasheet; we follow the datasheet. A value that the sources do not state is shown as not stated.
We do not show prices, because they depend on the installer's quote.

Common questions about GivEnergy 9.5 kWh Battery
How much does the GivEnergy 9.5 kWh battery store?
GivEnergy lists 9.5 kWh nominal (186 Ah at 51.2 V) with 100% depth of discharge. It does not give a separate usable capacity.
Does it include an inverter?
No. It is a battery only. GivEnergy positions it for its third-generation inverter range, so ask your installer which inverter it pairs with.
How long is the warranty?
The UK datasheet states 12 years with unlimited cycles. GivEnergy's product page shows 12 years in one place and 10 years in another, so confirm the terms with your installer before you buy.
